Specification forming part of Letters Patent No. 165,440. dated July 13,1875; application filed December 22, 1874.

To all whom t may concern Be it known that I, MICHAEL FITZPAT- RICK, ofthe city of St.l Louis, in the county of St. Louis and State ofMissouri, have invented certain new and useful Improvements inFirePlaces and Open Stoves; and I do hereby declare that the followingis a full, clear, and exact description thereof, which will enableothers skilled in the art to which it pertains to make and use the same,refer ence being had to the accompanying drawings, and to theletters ofreference marked thereon, which form a part of this specification.'

Figure 1 is a vertical section on line a' :v of Fig. 2. Fig. 2 is afront elevation, partly in section. Fig. 3 is a top view of thetire-place with sheet-iron hood removed. Fig. 4 is a perspective view ofone side piece or jamb.

This invention relates to improvements upon the patent granted to me May12, 1874, No. 150,680, Afor a re-place grate, a-s will be hereinafterfully described.

A A are the two side jambs, in whichopposite to each other and beingright and leftare the recesses into which the upright back and the footpieces are to be inserted, which are represented by B and C, one of thembeing in perspective in Fig. 4. D is a damper-plate, which has on itsupper side near each end cogged racks d d and projectingstifteningbraces d d" d.

E is another dampenplate above D, as seen in Fig. 1, and which vibratesloosely1 in its recess F, which is V-shaped, and in Fig. l is seen intwo positions, open andb closed; itsV purpose is to narrow thechimney-flue partially when required. G is a small shaft placed ou oneside, and supported by the ends of a clamp-frame, f j", which holds thesides together. On this shaft G is a beveled gearwheel, g, which meshesinto another beveled gear-wheel, g', on a shaft transverse to G, andwhich runs through the iire-place from outside, having on it two coggedspur-gears, d d,

` which operate upon, the racks d d on the back -of the damper-plate. His a sheet-iron hood or smoke-stack, which is made several inchessmaller than the size of chimney-flue above, and ts snugly upon the topof the jambs,

and also has an apron, h, which comes down in front as far as maybedesired to protect the face of the mantel-piece, as seen in Fig. 2 infront elevation, a part of it beingbroken away to show the liningsheet-iron H El', by

which a space, hf, is formed, so that the hot smoke in the middle isseparated from the colder in the corners and sides. A wire can beattached to the upper end of the damper D, and passed through a hole inthe apron h, and can be used to elevate the damper, when the gearedapparatus can be dispensed with; but by the handle g on shaft G is theusual method of controlling the damper. Another plan is shown in Fig. 1,where a lever, l, is pivoted at l', and is attached to the damper, andis operated by a handle L, which comes out below t-he grate and abovethe fender. T he jainbs, which are held at the top in the back by theclampplatesff, are also held by through-bolts a a a aJ at the top andbottom, and at m is a rod, by which thewhole work is secured to the backwall.

The jambs A A and cross-plates B and C can be made of lire-clay, tile,or soap-stonethe jambs to be molded with recesses, as shown, for thereception of the other pieces, B and G. By the manufacture of the jambswith recesses to be adapted for the reception of the cross-pieces, withthe holes for the tierods a a and the recesses on the reverse sides forthe iron clamp-frame f j', the complete fire-place can be put up and beoiiered for sale as an article of manufacture, to be adapted foranyordinary nre-place in buildings already constructed, and by whichtheir defects may be obviated and smoking 0f chimneys be prevented. Thesheet-iron hood and hot-air lues may be used, if required, and iitted tosuch rines and chimneys; the apron serves a valuable purpose, also, ofpreventing the radiating heat of the coal re'from aftectin g the wood`or marble fascia. above the arch or opening.

The lining of the flue serves the purpose of dividing the ascending airand gases, so that the hotter portions in the middle will serve tocreate a draft above, to cause the side portions, which are colder, tohe driven up much faster than if all were to be in the same flue, asheretofore. In a former patent, issued to me May 12, 1874, for afire-place, the damper VHavingdescribedmy inven tion,whatlcla1m,

was operated by a shaft with one cogged wheel in the middle of thedamper, which it is found does not operate always with ease. In thepresent application two racks and wheels are used, which is a greatimprovement over the old method; also, the hot-air ilues are placed onthe sides and rear, as at k k', Fig. 2, so that heated air can becarried up the flue of the chimney by pipes k k', and into the upperrooms, and also be brought into the same room, if required.

and desire to secure by Letters Patent, is

The double smoke-flue in the sheet-iron hood, in combination with afire-place or grate, substantially as and for the purpose described. Intestimony that I claim the foregoing as my own invention, I aix mysignature in presence of two witnesses. MICHAEL FITZPATRICK.
